    Low water use efficiency is a challenge to crop production in Sub-Sahara African countries. Water is getting continuously scarce due to increased demand and shrinking availability induced mainly by climate change. As agriculture is the major consumer of water, improving crop water productivity is among the ways of overcoming the challenge. Crop production under rainfed system is the major livelihood strategy for smallholder farmers in Ethiopia.

    This study conducted in two sub catchments of the Abay Basin identified the quantity and quality of sediment loss and its origin though most studies conducted in Ethiopia focus on quantification of soil loss. Also, the onsite economic cost in terms of yield reduction was estimated taking maize (Zea mays) as representative crop. For this purpose, two monitoring stations were selected at the outlet of the two watersheds. Depth integrated runoff samples were collected during the rainy season in 2011 while discharge of the Rivers was estimated from staff gauge-discharge relationship.

    In Ethiopia, soil erosion during the rainy season constitutes a sever threat to the national economy. The study site, head of the Abay basin is among the heavily affected areas, which is a peril for the crop water productivity. Most studies conducted in the country are focused on quantification of sediment and lack of specific information about temporal and spatial variability of sediment and its associated plant nutrients loss.
